What makes North Carolina different
The other thing that makes the arithmetic here unusual is that the fine is often the smaller half. North Carolina attaches fixed court costs to every traffic conviction, set by statute rather than by the county, and on a minor citation those costs comfortably exceed the fine itself. A driver comparing the fine figure against another state is comparing the wrong number.
And North Carolina keeps a remedy almost no other state has: the Prayer for Judgment Continued, which can leave a driver convicted of nothing at all. It is limited, it is discretionary, and it is worth understanding before deciding what to do with a citation.
